Application filed March 25, 1918.

To all whom it may concern:

Be it known that I, BERNARD HAUsMANN, a citizen of the United States, residing in the borough of Manhattan of the city of. New

orx, in the State of New York, have-invented certain new and useful Improvements in Windows, of which the following is a specification, reference being had to the accompanying drawings, forming a part iereof.

This invention relates type known as doublehung, in which the sash oreach sash may slide vertically and may also swing inward to a greater or less extent for the purpose of permitting ventilation without draft and also for permit- 7 e cleaning of the window on both sides, without requiring the cleaner to stand Various forms of double hung windows have been devised, allrequiring window fittings or hardware of a considerably expensive nature. The present invention has for its general purpose to provide means whereby a doublewhich porting chain, and is provided, at a suitable point above the point of attachment with a device which, as soon as'the inward swinging movement of the .one end, is connected at the other iung sash can be supported andoperated with fittings or hardware much less expensive than that commonly employed and.

therebyreduoing largely the factor of cost has prevented the more gen eral use of double-hung windows. In accordance with the invention the supporting chain at each side of the window, to which the counterbalance weight is connected at end to the sash, preferably by may be regarded aspart of the supto the sash,

Window begins, engages a device fixed to the frame or casing so that the sash s then locked against vertlcal movement. Means are also provided whereby the inward swinging movement of the sash can take place only when the sash is at or nearits lowest position. The invention will be more fully explained hereinafter with reference to theaccompanying drawings in which it is illustrated, and in which Figure 1 is. a view in vertical section of.

a' window which embodies the invention, the sash being shown as swung inward.

2 is a detail view in perspective, and in section through the casing, on a larger scale than that of Fig. 1, a portion of the lower sash being broken out.

Specification of Letters Patent.

to windows of the the top of the inner sash a long link or arm one end to a counterbalance arm or link Patented Feb. 17, 1920. Serial No. 224,468.

Fig. 3 is also a detail view in perspective illustrating particularly the relation of the locking devices of the two sashes to the frame or casing of the window.

Figs. l and 5 are detail views illustrating a modification to be described.

in the embodiment of the invention illustrated in Figs. 1, Stand 3 of the drawings, the lower sash a and the upper sash b are arranged to slide as usual in a casing c. In the present instance, in orderthat the upper sash b may swing inward when in its lowest position, the head of the casing, as at c, is arranged to receive the top of the lower sash, so that when the lower sash is raised tov its highest position the upper sash, then in its lowest position, may swing under the other sash. Each sash slides as usual in its own track. The track for the lower, .or inner, sash may have no inner stop bead in its lower half or in its upper half, a stop (Z, having a movable member d, being provided just above the plane of when in its lowest position and serving to prevent the inner sash from moving bodily inward when in any position above the lowest and servin also, through the movable member cl, to prevent the swinging inward of the inner sash when in its lowest position unless such swinging movement is desired.

inward The track for the upper or outer sash has a stop bead c in its upper half, to prevent the sash from movinginward except when in its lowest position, but the lower half of the track may have no stop bead at all, or a movable stop bead, so that the outer sash is free to be. swung inward when in its lowest position.

Each sash chain or cord 6, connected at weight, not shown, passes-over a pulley c and is connected to the sash at a point preferably below-the middle ofthe sash. The casing and the sash are formed so as to receive the chain between them as usual. Preferably each chain or cord is connected to the sash through a link or-arm e which may be regarded as a part'of the chain or cord. The is pivotally connected at its lower end to the sash, as at 6 near the middle of its vertical side, and is also pivotally connected, as at e, to the flexible por- ;.:Figs. 1, 2 and 3, tended from the the casing 0. v
